The molecular determinants of a healthy human liver cell phenotype remain largely uncharacterized. In addition, the gene expression changes associated with activation of primary human hepatic stellate cells, a key event during fibrogenesis, remain poorly characterized. Here, we provide the transriptomic profile underpinning the healthy phenotype of human hepatocytes, liver sinusoidal endothelial cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as activated HSCs (aHSCs)

View SamplesWe find that sub-set of cytokin repsonse genes are not regulated at WT levels in the bpc1,2,3,4,6 mutant. Overall design: Whole ten-day-old seedlings of WT and the bpc1,2,3,4,6 mutant were treated with synthetic cytokinin (benzyladenine) or a vehicle control (NaOH) for 1 hour and root tissue was isolated.

View SamplesWe surveyed DNA methylation profiles of all human RefSeq promoters in relation to gene expression and differentiation in adipose tissue, bone marrow and muscle mesenchymal progenitors, as well as in bone marrow-derived hematopoietic progenitors. We unravel strongly overlapping DNA methylation profiles between adipose stem cells (ASCs), bone marrow mesenchymal stem cells (BMMSCs) and muscle progenitor cells (MPCs), while hematopoietic progenitor cells (HPCs) are more epigenetically distant from MSCs seen as a whole. Differentiation resolves a fraction of methylation patterns common to MSCs, generating epigenetic divergence.

View SamplesIn order to assess whether culturing adipose-derived adult stem cells (ADASCs) affect their gene expression (see Sample Growth Condition Protocol), we wanted to identify possible genes that were differentially expressed between cultured polyclonal CD31- ADASCs and freshly isolated (uncultured) polyclonal CD31- ADASCs. To that end, RNA was isolated from cultured and uncultured ADASCs from three different donors and analyzed using the Affymetrix Microarray HG-U133A. Then, using the Affymetrix program MAS 5.0 we performed three comparisons and could identify differentially expressed transcripts common between the three donors, using the Affymetrix program DMT 3.0.
